ghg emissions footprint from potential feedstock production of biodiesel fuel (case study)

population growth and increasing industrial and agricultural activities that cause ghg emissions and risk from environmental management is a serious challenge. in this research, the ghg emissions from peanut production as a potential feedstock for biodiesel fuel was investigated. data were collected through interviews with 75 peanut farmers. the cultivated areas were divided into three categories based on the size of peanut farms as 0.1–0.5 ha, 0.5-1 ha and larger than 1 ha. the results revealed that total ghg emissions of peanut production was obtained 822.29 kg co2eq ha-1. the highest share of ghg emissions belonged to diesel fuel (57.90%) followed by machinery (18.6%).the mean difference between total ghg emissions per unit area among farm sizes including 0.1–0.5 ha and larger than 1 ha was significant at 5% level. larger farms from 1 ha had the minimum amount of ghg emissions. also, ghg emissions from peanut production as a potential feedstock for on liter biodiesel fuel production were calculated 1.17 kgco2eqha-1.
